Thermostatic baths / liquid baths / temperature calibration baths can be filled with three different types of substances:
LR-Cal DRUCK & TEMPERATUR Leitenberger GmbH - in its standard temperature calibration baths - does not use biphasic fluids since, although their temperature field is very wide, they are very dangerous and ca cause explosions in particular working conditions.
LR-Cal DRUCK & TEMPERATUR Leitenberger GmbH does not manufacture temperature calibration baths / thermostatic baths / liquid baths using alumina powders since it is not possible to completely eliminate the powders that are continuously discharged from the bath opering, causing therefore some problems as far as environmental compatibility is concerned.
The liquids, sold by LR-Cal DRUCK & TEMPERATUR Leitenberger GmbH are mostly oils and glycol-based anti-freezing mixtures. The operating instruction of every single equipment contain an indication of the best liquid to be used for excellent performances.
||Recommenced usage field
|Temperature value above which an extractor hood should be used
|Fume burning point
|Equivalent temperature for 10cst viscosity
|Glycol 56% + water||-40...+90°C||+70°C||>110°C||+20°C||-43°C|
|*)||Recommended usage field:
range of temperature in which it is possible to use the liquid in LR-Cal baths, although the viscosity is not good to optain the best performances.
|**)||Temperature value above which an extractor hood should be used:
Temperature value above which an extractor hood should be used bcause the fume increases.
|***)||Fume burning point:
Temperature value on which steam triggers off in the presence of free flames.
|****)||Equivalent temperature for 10cst viscosity:
Temperature value below which the thermostatic performance is no longer excellent. The viscosity value tends to decrease as temperature increases. The equivalent water value at 23°C is 1cst
Temperature value below which the liquid changes its state and solidifies.
The calibration liquids are degenerated during usage. As higher the temperature and as longer the time of high temperatures, as faster is the degeneration of the fluid. For this reason: avoid high temperatures for longer times.
